OLD OR DIRTY HOT TUB FILTERS ARE THE #1 REASON FOR SERVICE CALLS.

Hot Tub Works recommends that you change your spa filter at least one time a year! A fresh hot tub filter helps protect your health AND your pocketbook. Who wants to buy replacement spa parts when that money could be saved (or, better yet, spent on fun hot tub accessories?). Dirty hot tub filters can even void your warranty. So, it pays to check your spa filter once or twice monthly.

If your spa filter is more than two years old, you should toss it no matter how it may look. This is because your hot tub filter is made of a fibrous material that gradually loosens over time creating ever-larger spaces for particles to push through and gunk up your pump. It pays to be ruthless on this one. Hot tub pumps are way more expensive than spa filters. Consider it a law: two years and it's hasta la vista, baby!

This method will most likely lead to multiple results from which you can compare filters.
